Prosperity Froggie

We would usually expect to see frogs or toads in our night shoots if it rained in the day. This night promised as such, as we set forth to locate the prosperity frog (it's just a name we gave it) after a day of rain.

Spotted Tree Frog (Nyctixalus pictus) - DSC_0553 #1 Found the prosperity froggy, thanks to Marcus and James. Nyctixalus pictus.

Spotted Tree Frog (Nyctixalus pictus) - DSC_0556 #2 Prosperity Froggie because it is orange. 大吉大利!

Spotted Tree Frog (Nyctixalus pictus) - DSC_0571 #3 Oblivious to our presence, we could even rotate the froggie around on the leaf without it jumping off. Extremely flat little froggie.

Spotted Tree Frog (Nyctixalus pictus) - DSC_0582 #5 Placed the flash under the leaf to get an "X-ray" of the froggie.

Wolf Spider (Lycosidae) - DSC_0547 #11 And closer!!

Orb Weaver Spider (Araneus sp.) - DSC_0549 #12 Possibly a Kidney Garden Spider (Araneus mitificus)?

Harvestman (Opiliones) - DSC_0612 #13 Harvestman with a spikey green back

DSC_0626 #15 Unique looking bug with cyan stripes on it's abdomen

Scorpion (Lychas scutilus?) - DSC_0630 #16 Usual scorpion on a tree bark

Scorpion (Lychas scutilus?) - DSC_0634 #17 Lighted with Ultra Violet

Scorpion (Lychas scutilus?) - DSC_0638 #18 Ultra Violet mixed with flash

Scorpion (Liocheles australasiae?) - DSC_0726 #19 Not so common scorpion, Hemiscorpiidae?. Refused to stop moving. Some of them had smaller pincers, which I suspect to be females of the same species?

Scorpion (Liocheles australasiae?) - DSC_0728 #20 Tiny tail, I wonder how it manages to sting the prey? Likely to swing from the side like a crocodile.

Scorpion (Liocheles australasiae?) - DSC_0733 #21 Lighted with Ultra Violet again.

Scorpion (Liocheles australasiae?) - DSC_0735 #22 Final shot. I was waiting for a mating pair but they just wouldn't come out from beneath the tree bark.

To find out why scorpions glow under Ultra Violet light, refer to my previous post:
Beetle (Coleoptera) - DSC_0746 #23 Scarab beetle?

Beetle (Coleoptera) - DSC_0753 #24 Couldn't retract it's wings

Dragonflies (Anisoptera) - DSC_0757 #25 Two dragonflies at rest

Dragonfly (Anisoptera) - DSC_0766 #26 They were beautifully covered with dew

Ovipositing Wasps

Oviposition is the process of laying eggs with little or no embryonic development within the mother. Some wasps need to lay their eggs inside foreign hosts. The mother goes in search of larvae of other bugs beneath the wood/bark using her antennae, and is able to pierce her ovipositor through to the foreign host to lay her eggs. (Source: Giant Ichneumon Wasp)

We found a tree with numerous wasps, possibly Stephanidae in various stages of oviposition. In fact, many of them were ovipositing again and again on the same tree, allowing us to witness the entire process. Unfortunately, many were also found way above our eye-level and we ended up with shots at weird angles.

Crown Wasp (Stephanidae?) - ESC00035 #5 Rear view, showing that the ovipositor had already been pierced through a significant distance.

Crown Wasp (Stephanidae?) - ESC00051 #6 Ovipositor completely driven into the tree trunk

Crown Wasp (Stephanidae?) - ESC00056 #7 The wasp remained in this position for a few minutes

Crown Wasp (Stephanidae?) - ESC00129 #9 Another oviposition in progress while an ant comes by to disturb

Crown Wasp (Stephanidae?) - ESC00137 #10 Final shot before we made our way into the trail

Planthopper? Leafhopper? - DSC_9948 #11 Warming up with planthopper

DSC_9949 #12 Another planthopper? Very cute, almost like a ladybird.

Wrap-around Spider (Dolophones sp.) - DSC_9964 #13 A branch-hugging spider, likely to be a species of Dolophones (Araneidae). Kindly IDed by David Court.

Tailless Whip Scorpion (Ambyplygi) - ESC00146 #22 Full body view. The body alone spanned about 2cm. This was the last shot before the rain came pouring down.

Micro Movements in the Cyrtarachne

2 years ago, I posted some examples of bugs which exhibit micro movements when they appear to be at rest when viewed with the naked eye. It was only much later that I managed to document this movement in the Bird Dropping Spider (Pasilobus sp. Cyrtarachne fangchengensis) when I found one and actually remembered to shoot it. :P

Note: ID corrected to Cyrtarachne fangchengensis according to the Singapore Biodiversity book.

Frog Mimic or Bird Dung Spider? (Cyrtarachne sp.) - DSC_9203 #1 The Bird Dropping Spider (Pasilobus sp. Cyrtarachne fangchengensis) with an unidentified fly plastered onto the abdomen

Bird Dung Spider (Cyrtarachne sp.) - DSC_9227 #2 The micro movements. I do not have any verified theories to these movements, but my first thought was that it was due to the movement of digestive juices in the spider. David Court had suggested that it could also be a anti-predator warning device.

Huntsman Spider (Sparassidae) - DSC_9179 #3 A juvenile Huntsman Spider

Unknown eggs - DSC_9194 #4 Unidentified eggs, looked like golden eggs!

Wolf Spider (Lycosidae) - DSC_9261 #5 Female Wolf Spider (Pardosa pseudoannulata?) carrying an egg sac

Wolf Spider (Lycosidae) - DSC_9270 #6 Front view of the same wolf spider

Jumping Spider (Siler sp.) - DSC_9275 #7 A Jumping Spider (Siler sp.) captured this planthopper nymph while we were observing it.

Jumping Spider (Siler sp.) - DSC_9278 #8 It loved to raise it's 2 fore-legs in this manner. To ward off predators perhaps?

Jumping Spider (Siler sp.) - DSC_9281 #9 Yes, still doing it. Surrender? lol

Jumping Spider (Siler sp.) - DSC_9283 #10 Back view. Very colourful abdomen

Jumping Spider (Siler sp.) - DSC_9297 #11 Top view. We were hoping that this was a peacock spider, but it was not to be. :P

Crab Spider (Thomisidae) - DSC_9317 #12 Relatively large Crab Spider (Angaeus rhombifer)

Crab Spider (Thomisidae) - DSC_9324 #13 Top view of the crab spider

Caterpillar - DSC_9330 #14 Unidentified caterpillar, with a very stout body and vibrant colours

Tree Stump Orb Weaver Spider (Heurodes sp.) - DSC_9441 #23 Side view of the tree-stump wannabe. The abdomen is thinner than the previous ones that I had shot before:

Tree Stump Orb Weaver Spider (Heurodes sp.) - DSC_9452 #24 Managed a portrait shot. This was already focused to infinity with the Raynox 250 slapped on.

Crab Spider (Thomisidae) - DSC_9471 #25 Another Crab Spider (Angaeus rhombifer)

Crab Spider (Thomisidae) - DSC_9485 #26 Front view of the eyes.

Orb Weaver Spider (Araneidae) - DSC_9490 #27 This spider caught my eye with the jade-green abdomen. Probably a Kidney Garden Spider (Araneus mitificus)

DSC_9499 #28 Unidentified fly?

Wandering Spider (Ctenidae) - DSC_9516 #29 Wandering Spider (Ctenus sp.) on the ground, munching on a roach
